Vedclass · Answer

(C) The octet rule states that atoms tend to gain,lose,or share electrons to achieve a stable configuration of $8$ electrons in their valence shell. In $CO_2$,$C$ has $8$ electrons and $O$ has $8$ electrons. In $CHCl_3$,$C$ has $8$ electrons,$H$ has $2$ electrons (duet rule),and $Cl$ has $8$ electrons. In $NH_3$,$N$ has $8$ electrons and $H$ has $2$ electrons. In $ClF_3$,the central atom $Cl$ has $10$ electrons in its valence shell ($3$ bonding pairs and $2$ lone pairs),which is an expanded octet. Therefore,$ClF_3$ does not obey the octet rule.

Which of the following molecules does not obey the octet rule?
